We are using the filter widget in one of our apps, which is fine if you're only picking one value, but some users have a need to select more than one value to display on the map. For instance, we have a feature class with AVL data and the vehicles are grouped into "Group Name". Selecting a Group Name will only display the vehicles associated with that group on the map. This is fine if you only need to see one group, but it doesn't work if you want to see more than one. There is no "Control + Select" in Web AppBuilder.
So, the ideal solution would be a widget that has a drop down list of possible values with a checkbox next to each one. You check the box next to all the groups you want to see, click "Apply", and then those are the values displayed.
I would assume that there are many others needing this, but I have yet to find a widget that has this functionality. I did find the jquery sample for "Bootstrap Multiselect" and it's exactly what I need, but I'm unsure how to incorporate this into a custom widget: https://github.com/davidstutz/bootstrap-multiselect
Anyway, just wondering if this has been done before. Any help would be much appreciated.
