    -name name [ spec ]

Defined in packages/categories/tcl/category-list-procs.tcl

Adds list-elements to display mapped categories. To be used in list::create.

Scenario:
you prepare a multirow which is then displated via template::list::create

Usage:
you change the list query by adding an outer join to category_object_map and selecting the object_id and the category_id. After having built the multirow holding the list of objects you add a call to

    category::list::collapse_multirow -object_column <<columnname-holding-object_id>> -name <<multirowname>>

to collapse the multirow so that it holds only one row per object with a tcl-list of mapped categories in the category column.

After you got the multirow, use

    category::list::prepare_display -name <<multirowname>> -container_object_id $package_id

(or an object other than package_id that the trees are mapped to). This proc will generate one extra multirow column per mapped tree that will hold a pretty list of the categories. The pretty list can be changed with various options (delimiter, links etc). If you want to have only one extra multirow column holding a pretty list of the mapped trees and categories, then you should use the -one_category_list option.

To automatically generate the appropriate input to be used in the elements section of template::list::create, use

    category::list::elements -name <<multirowname>>

followed by extra spec to be used per element. Again, to display only one column use the -one_category_list option.

Switches:

-categories_column (optional, defaults to "categories")

beginning of the names of the multirow columns holding the category-names.

-tree_ids (optional)

trees to be displayed. if not provided all tree columns in the multirow will be displayed.

-locale (optional)

locale to display the tree-names in columns.

-one_category_list (optional, boolean)

switch to generate only one additional column in the list that holds a pretty list of tree-names and category-names.

-name (required)

name of the multirow for the list.

Parameters:

spec (optional)

extra spec used for the list-elements. you can override the display_template with using "categories" as column holding the pretty list of category-names.
