kotti_navigation 0.3.1

Add a configurable navigation to your Kotti site

This is an extension to the Kotti CMS that renders a navigation in one of the available slots for a Kotti website (left, right, abovecontent, etc.).

Setting up the navigation widget

These are the configuration settings we will be discussing here for the navigation widget::

# general navigation widget settings, showing defaults
kotti_navigation.navigation_widget.display_type = tree
kotti_navigation.navigation_widget.show_context_menu = false
kotti_navigation.navigation_widget.label = none
kotti_navigation.navigation_widget.slot = left
kotti_navigation.navigation_widget.open_all = false
kotti_navigation.navigation_widget.show_hidden_while_logged_in = true
kotti_navigation.navigation_widget.exclude_content_types = (e.g., Image)
kotti_navigation.navigation_widget.include_root = true

# specific to list display
kotti_navigation.navigation_widget.show_dropdown_menus = true

To set up the navigation widget to display on every page in Kotti in the default left slot as a tree display, add an entry to kotti.configurators in the .ini config file for your project::

kotti.configurators =
    ...
    kotti_navigation.kotti_configure

Here are the slots available for the navigation widget::

left
right
abovecontent
belowcontent
belowbodyend

which you set with a config parameter::

kotti_navigation.navigation_widget.slot = abovecontent

Note

Configure navigation for only one slot.

Here are the slot choices in a layout diagram::

+------------------------------------------------------+
| nav (the nav in the Kotti toolbar -- configurable)   |
|------------------------------------------------------|
| editor_bar                                           |
|+----------------------------------------------------+|
|| breadcrumbs                                        ||
|+-------------++---------------------++--------------+|
|| SLOT "left" || SLOT "abovecontent" || SLOT "right" ||
||             |+---------------------+|              ||
||             || Content             ||              ||
||             |+---------------------+|              ||
||             || SLOT "belowcontent" ||              ||
|+-------------++---------------------++--------------+|
| footer                                               |
|------------------------------------------------------|
| SLOT "beforebodyend"                                 |
+------------------------------------------------------+

Configuring to Replace Top Nav

You see the top nav position in the diagram above (it is not a slot), where default Kotti puts the nav.pt template. kotti_navigation provides a nav.pt that can replace Kotti’s nav.pt::

kotti_navigation/kotti-overrides/templates/view/nav.pt

that can be enabled in your ini file with::

kotti.asset_overrides = kotti_navigation:kotti-overrides/

This will tell Kotti that you are selecting any templates that are defined within kotti_navigation:kotti-overrides and which match Kotti’s directory structure for templates.

This top position is not a slot, so make sure to omit the slot setting or to set it as::

kotti_navigation.navigation_widget.slot = none

For this top position, you will probably want to configure these nav settings as::

kotti_navigation.navigation_widget.display_type = list
kotti_navigation.navigation_widget.show_context_menu = true

and you probably want to omit the label setting. The breadrumbs may in this usage be deemed redundant. If so, override Kotti’s master template to omit it (See below, under discussion of display_type).

The default development.ini config file has a tree nav in the left slot. See the alternate top.ini for an example of a configuration replacing nav.pt.

Excluding the Root

To exclude the root of the site from the navigation, in either the tree display or the context menu of the list display, set this::

kotti_navigation.navigation_widget.include_root = false

Excluding Content Types

You can exclude specific content types from the whole navigation structure. If you not want to show images in the navigation at all, set the kotti_navigation.navigation_widget.exclude_content_types variable to the following::

kotti_navigation.navigation_widget.exclude_content_types =
    kotti.resources.Image
    kotti_myaddon.resources.MyContentType

Setting Display Type

Control the type of display with the display_type setting, which can be either list (default) or tree::

kotti_navigation.navigation_widget.display_type = list

Configuring the tree display is straightforward; you have the choice of including the root, or not. The navigation tree shows the full site content in an indented vertical list. When an item with children is clicked, it is exploded, and with another item is clicked, it is collapsed. The tree display is most appropriate for the left and right slots, but can be used in any other slot, probably accompanied by customization through CSS.

The list display does not show the full site content; Only the immediate children for the context are shown as a simple list of navpills wrapped within the available space. This navigation menu can be used in two ways, regarding the breadcrumbs display in default Kotti:

  • Turn off the context menu for the list display with show_context_menu set to false, and use Kotti’s breadcrumbs display for providing essential navigation back up the site hierarchy
  • Turn on the context menu fo the list display, and turn off Kotti’s breadcrumbs display by overriding via templates. The context menu will provide an active link to go up one level from the current context, and will provide links to the root and top-level content items.

The list style of display is different for “horizontal” vs. “vertical” aspect slots, as follows:

  • In the abovecontent, belowcontent, and belowbodyend slots (“horizontal” aspect), the list display is akin to the display of tags as nav pills wrapping horizontally within a container filling the slot, plus a label and/or context menu item button if they are configured to be present.
  • In the left and right slots, the list display is the nav-list style from Bootstrap, which shows items in a more traditional “vertical aspect” list format.

Note

Regarding the default top nav-bar in Kotti, to avoid redundancy, you may want to override the nav.pt view template, or remove it from master.pt, so that there are no nav items shown in the top bar.

Configuring a Label

There is an optional label for the top of the tree display, underneath the context menu if it is enabled, or for the first item in the list display.

For the following discussion about the optional label, the context is assumed to be a document titled Animals, and there are two children titled Dogs and Cats.

A label for a tree display

The optional label at the top of the tree dislay would usually be set to none, because the nature of the indentation should make the context obvious. In some situations, however, a simple label such as “Site Navigation” or “Site Menu” could be desired. To set such a label, do::

kotti_navigation.label = Site Menu

Note

String params in ini config files do not have quotes, so the string is whatever comes after the = sign, with leading whitespace deleted.

The current context will be indicated by the highlighting of the context menu item in the tree display. This is normally adequate. However, for extra clarity, or for some special reason, you may want to include the current context in the label, in a phrase such as “Current item: context”, where the word context would be replaced by the actual context.title, e.g. “Current item: Cats”. So, include the actual word context in the label text::

kotti_navigation.label = <context>

(the label would become ${‘<’ + context.title ‘>’} in the template code, which would become <Animals> in the rendered label.)

Or, if the site’s breadcrumbs display is not shown, by overriding templates, and you want to have a simple replacement in concert with the tree display, do::

kotti_navigation.label = You are here: context

(You are here: Animals).

A label for a list display

If using a list display for navigation, the default will list children of the current context in a list of nav pills that wrap, if necessary. Along with the default Kotti nav toolbar and and breadcrumbs, this may provide a perfectly good nav display. When the abovecontent slot is used, however, the title for the context is _underneath_ the nav list, so it may not be clear enough that that the nav pill items are children within the context. Perhaps this would be true for the left slot, as well, but a bare nav pill list in the right and belowcontent slots might work well.

If label is not set, the default value of none will result in two nav pill li items for the example Animals context::

<Dogs> <Cats>

(< > notation used here to denote nav pill li items).

Using a custom string, punctuated with a colon::

kotti_navigation.label = Contained Items:

would result in a nav-header styled label with two nav pill li items, as::

Contained items: <Dogs> <Cats>

or, perhaps with some other punctuation::

kotti_navigation.label = Contents >>

etc.

As described above, set label to a string using the word context anywhere in the string as a placeholder for context.title.

kotti_navigation.label = context

The result would be a label for Animals and two nav pill li items, as::

Animals <Dogs> <Cats>

With any punctuation or additional text of any sort along with context in the label, as with::

label = context:

becomes::

Animals: <Dogs> <Cats>

If a phrase is used, take care to word appropriately, perhaps aided by use of quotes or another indicator for context, such as (), [], etc.::

kotti_navigation.label = Items in [context] are:::

would result in::

Items in [Animals] are: <Dogs> <Cats>

and::

kotti_navigation.label = "context" contains:

would result in::

"Animals" contains: <Dogs> <Cats>

etc.

Configuring for Use with a Menu System

To open the whole navigation all the time, set the open_all variable. This is useful if you plan to set up a popup menu via css or javascript::

kotti_navigation.navigation_widget.open_all = false

You will want to set display_type to tree, because the list shows, by design, only the children of the current context. The tree display, when open_all is true, will produce items for each node in the full tree.
