Track selector

How do I add categories to the Hierarchical data selector?

The hierarchical data selector can support multiple levels of drop down categories. To use this, set the "category" variable on your track, and use a "/" to represent a subcategory. Use multiple / for multiple subcategories.

Example

    {
     "category": "ParentCatgory / DiseaseBAM",
     "label": "myTrack",
     "storeClass": "JBrowse/Store/SeqFeature/BAM",
     "type": "Alignments2";
    },
    {
     "category": "ParentCatgory / NonDiseaseBAM",
     "label": "myTrack2",
     "storeClass": "JBrowse/Store/SeqFeature/BAM",
     "type": "Alignments2";
    }

In tracks.conf form

[tracks.myTrack]
category=ParentCategory / DiseaseBAM
type=Alignments2
storeClass=JBrowse/Store/SeqFeature/BAM

How do I collapse categories in the Hierarchical data selector by default?

You can set the following config

collapseCategories=ParentCategory1/ChildCategory,ParentCategory2/ChildCategory

etc. to your jbrowse.conf. This is a comma separated list (don't include spaces around the slashes though). Remember, don't quote the values in the jbrowse.conf file :)
