How can I config window with resizable border?
The jQuery sample:
https://jqueryui.com/dialog/
There is no way to do it for now, but it will be added in one of next builds.
Can you share a bit more info, why it is necessary in your case. Window can adjust self to the inner content, so in most cases you will need not a custom resizer.
case 1: show html content for the item in the search list:
{ view: template, template: “http->api/contents/1234” }
case 2: quick text editor (text area, html wysiwyg - ckeditor, tinymce,…)
case 3: popup grid, tree (for filters, as navigation)
case 4: import-export csv text (window opens on button click)
For (1) and (3) autoheight can be used on template, grid or tree
For case (2), yep you are right.
I have added this feature to the roadmap.
