# CategoryURL - JBrowse plugin

Add URL parameter "cat" to specify a category of tracks to display.
All tracks with the given category will be displayed.
If any "tracks" are specified in the URL, "cat" tracks will be appended to list.

Usage: Add `&cat=myCategory` to the URL
Result: all tracts with category "myCategory" will be displayed.
Sub-categories are supported as well (i.e. `&cat=myCategory/mySubCategory`)

The cat= URL parameter allows the display of tracks with the given category 
defined in the track metadata that are used to group tracks in the hierarchical 
track selector.  For example:

    "category" : "Miscellaneous",

Example:

    http://<jbrowse>/?data=sample_data/json/volvox&cat=Miscellaneous

    http://<jbrowse>/?data=sample_data/json/volvox&cat=Quantitative/Density
