I am looking to create sub-filters for my data table visualization. For example, once you select a filter (ex. "colors") a new set of filters would then pop-up which correspond to only this filter (ex. "red", "blue", etc.). Is this possible? If so, how?
no, kind of. but also yes.
It's not possible in the data-table as you describe.
But the input-controls visualization might get you there (https://www.elastic.co/guide/en/kibana/current/add-input-controls.html). You can create a hierachy of controls using the
Parent control functionality.
