Bases: jdaviz.core.template_mixin.BasePluginComponent

Traitlets (in the object, custom traitlets in the plugin):

• items (list of dicts with keys: label, color)

To use in a plugin:

• create traitlets with default values

• register with all the automatic logic in the plugin’s init by passing the string names of the respective traitlets.

• use component in plugin template (see below)

• refer to properties above based on the interally stored reference to the instantiated object of this component

<plugin-subset-select
  :items="spectral_subset_items"
  :selected.sync="spectral_subset_selected"
  label="Spectral region"
  hint="Select spectral region."
/>
