BUG Missing FilterHeader in SiteTree listview

[ARNHOE]

Fixed silverstripe/silverstripe-framework#1492

[ARNHOE]

There is still a major flaw in this though. I can't get the filter away from LastEdited.

@chillu Any news on this pull request? Anything that needs to be improved or?

That's how it looks for me at the moment with this patch applied: http://db.tt/MTFVzb6Y

So we'll need the following:

• Show the filter by default, not only after sorting by lastedited
• Distribute the filter correctly between cells
• Allow filtering by name (so using a different column to filter than to display, since that contains HTML)

Given we're already tracking this in a bug, and this probably needs some deeper GridField work, i'll close this PR for the time being. Thanks for pushing to make the CMS UI better, anyway :)

See also #947.

@chillu note that the odd position of the arrow icon CSS background is due to the unusual implementation of this "child display" logic within a gridfield that GF may not have originally catered for.

Modifying GridField.css and adding min-width:12px; to thead tr.filter-header .fieldgroup "fixes" that, but of course leaves the issue you note that the magnifying icon should show by default.

Removed.
