filters

Layouts for exposed filters - i.e. you can move each filter into a region (supports Panels and Display Suite).

When I tried this (Summer 2018) the D8 branch wasn't really there yet - you could only rearrange the basic filter components in D8 (like search term, submit button, reset button), not all the extra ones you've added.   I went with using CSS (e.g. clear: both) instead.

My recommendation - safe to use but understand it's currently pretty limited due to bugs.

To activate, change a view's Exposed Form style (Advanced column) to 'Better exposed filters'.  

• Lets you enable AJAX auto submit. The difference is without BEF, with Use AJAX, an AJAX request (vs a full page reload) is made but ONLY when you click 'Apply'.  With BEF, as soon as you change a dropdown the view updates (like the filters on this site).  
• You can change the input method for each field (e.g.a single checkbox for what would otherwise be a True/False dropdown), make them "collapsible", add select all/select none links where appropriate.  
• Rewrite option that lets you reword all the options for the filter and also delete some.

Limitations:

• If you have a search field - e.g. Combine fields filter - you MUST turn on 'Exclude Textfield' if you are using 'Autosubmit'  
• Most of these options *aren't* available for taxonomies (e.g. webform where  
• If you use the default views single or grouped exposed filters, with selects/radios, they work correctly, but when you change them to BEF style, with checkboxes and AJAX, they don't (form is submitted and the checkbox has disappeared)
• Bug: reset button doesn't use AJAX, it sends you to a view URL instead (disable it in settings)

So all you can really do with BEF at the moment is use the AJAX setting.
