Visible expression of filter_select selection

DataStrategist opened this issue · comments

Hi! I'm working on a report using markdown and crosstalk. In an effort to make the report useable for differently abled users, we are looking at high-accessibility features. It was brought to my attention that it would be easier for people dyslexia and dyspraxia if making a selection added some text below specifying what has happened, for example:

Instead of:
image

We could have something like:
image

I have drawn the new text as a control, but it can be a modal popup, or part of the filter_select itself. It shouldn't be an on-hover property of the filter_select becuase title apparently isn't legible to screen-readers.

The other option I was considering is adding another object that can then be filtered by the filter_select, but then we have the problem that the default status shows all values.

Last case scenario is adding a clarifying note about what the filter_select will do in general, without changing to show the active selection... which is the low-tech but inferior option.
