Allow multi-select in filter drop-downs

[lebaphi]

Fixes #2874

[Tristina1788]

@IanMayo , @lebaphi Tested on '2874-multiple-select-dropdown' , now properties of dropdown is also selected multiple values

And I can select no option for dropdown list.

It think multiple values should be apply for 'Filter' panel.

Hello @lebaphi , while we need And between the separate filters, we need Or within the dropdown lists.

This setting should filter to include blue OR red. I'm pretty sure it's currently doing AND (which matches none, since it's impossible)

@lebaphi , @IanMayo Tested on '2874-multiple-select-dropdown' branch

Now Properties of dropdown is still enable to select multiple values

And the filter is And instead of 'Or'

Ok @lebaphi - we still have to block multi-select in the lower panel.

@lebaphi , @IanMayo Tested on '2874-multiple-select-dropdown', now the filter is 'OR' and dropdown list in 'Properties' panel only enable to select one.

But now the filter for 'Text' input with 'contains' instead of 'include' as before. I have to exactly text to filter properties.

Thanks @Tristina1788 , I will take a look on the text filter issue

[Tristina1788]

@IanMayo , @lebaphi Tested on branch '2874-multiple-select-dropdown' , now filter for 'Text' input work with 'include' as expected. And filter for dropdown is also working fine.

One bit still seems wrong, @lebaphi & @Tristina1788 . For an enum (dropdown) filter, it is showing features that don't have that field.

e.g. important and category. Features that don't have those fields are still included in the list. I'm pretty sure that if we filter for important: yes, then features that don't have the important field should not be shown. We should only show features that have an important field, and that it's value is yes

@IanMayo You are right. I can see this issue

[Tristina1788]

@lebaphi , @IanMayo Tested on '2874-multiple-select-dropdown' . Now filter is also works fine on 'Category' and 'Important'

Just one issue is filter gets reset to default filter when I added one more filter. I check on 'develop' branch and it has same issue. So I will create new ticket for it.
