CategoryBrowser creates a drop down list of categories. The amount of subcategories, pages or files can be filter and modified to make custom filters.
AJAX category tree browser shows subcategories of currently "expanded" category, very similar to Extension:CategoryTree, but also shows pages and files as well. Categories, pages and files are browsed via the pager (with limit count), to reduce the system resource consumption in large lists.

CB_Setup::$categoriesLimit = 10;
to set the limit (amount) of categories per page equal to 10.
CB_Setup::$pagesLimit = 10;
to set the limit (amount) of pages per page equal to 10.
CB_Setup::$filesMaxRows = 2;
to set the files pager to display maximum 2 rows in image gallery.
CB_Setup::$imageGalleryPerRow = 2;
to set the files pager displayed image gallery 2 images per row (default value is 4).
CB_Setup::$imageGalleryPerRow = 0;
to disable usage of image gallery (files pager will be identical to pages pager).
CB_Setup::$allowNestedParents = false;
to disable browsing of category parents (reverse browsing) (since v0.3.1).
CB_Setup::$allowNoParentsOnly = false;
to disable a checkbox for optional selecting of categories which has no parents only (since v0.3.1).
Go to Special:CategoryBrowser special page either by typing its URL in browser address line, or by clicking the same link at Special:Version or Special:Specialpages. The special page screen is divided into the following parts:
- Category filter form, which has three subsections:
- Top section has drop-down selector which allows to choose category filter condition either from the set of pre-defined ones, or from previously edited condition (stored in cookie). Also this section of form has "Search for category by name" field which allows to filter categories by first letters of the titles. This section is visible by default.
- When the condition filter was selected, two form sections with condition editor are also displayed. Middle section of the form shows currently selected condition filter divided into separate operators (condition line). Bottom section of the form displays "sample" operators to be modified and copied into the middle section, to create a used-defined condition filter (samples line).
- Category tree section, which displays categories matching the filter selected. When category has subcategories, click at the [+] sign displayed before it to expand it contents. Click "Pages" and "Files" links to display pages and files belonging to the selected category, respectively.
User-defined condition filter editing
Changing parameters of comparsion / logical operators are performed by directly altering input values in condition line. Another operations are performed by choosing small control buttons below the operator. Move the mouse cursor over the desired operator either in condition (middle) or in samples (bottom) line to display the operator's control buttons.
- To move current operator left, press [<-] control button in condition line. Operation will be performed only when the result does not produce invalid condition.
- To move current operator right, press [->] control button in condition line. Operation will be performed only when the result does not produce invalid condition.
- To delete current operator, press [x] control button in condition line. Operation tries to remain validity of condition line (for example, removing matching brackets; when removing condition operator, remove logical operator just before).
- To copy a new operator to clipboard, press [+] control button in samples line. The copied operator will be displayed in blue color. To clear the clipboard, press the same button twice.
- To paste an operator from clipboard before current operator, press [+] control button in condition line. Operation will always be allowed in the first and the last position of the condition line. Otherwise, editor's script will try not to allow to create invalid condition filter.
- To quickly copy/paste new operator from sample line to last position of condition line, press [>+] control button of the desired operator in samples line.
- To erase the whole condition ("select all"), press [=] control button of "All" operator in samples line.
- To apply the newly created filter, press "Apply" button.
- When the created condition is invalid, the erroneous operator is being shown in red / aquamarine colors. Also, "apply" button is disabled.
