XForms/Highlight Selected Row

MotivationEdit

It is very often useful to highlight the selected row. This is done with a xform-repeat-index pseudo element in the style sheet.

CSSEdit

By adding the following to your CSS the selected row will be highlighted in blue:

     .xforms-repeat-index {
        background-color: blue;
      }


Screen ImageEdit

This example highlights the background of the selected row. Xforms-hilight-index.jpg

This example was run using the FormFaces system.

DiscussionEdit

Note that this only works when you select a row an click your cursor on the input field. The result is that the value of the index for the selected list will change. This can be used by the functions that add or delete a selected row.

Known bugsEdit

This appears to not be functional under the FireFox extension as of 0.6.
