[BasicUI] There is no way to see abbreviated with `…` values

[dilyanpalauzov]

When the value of an item does not fit in the area, BasicUI 5.1.0 build 4923 hides the label and abbreviates the value by using …. Reducing the number of columns, utilized by BasicUi, could help to some extend to present to the user the full label and value.

In particular when clicking on a Selection item the label of the item should always be shown, even if before clicking on the item the label was fully displayed. This is useful in situations where the user clicks on a Selection, then does some unrelated things and after a while returns to BasicUI seeing a open dialog to change a value, but does not remember which item was clicked.

• When the user clicks over an item in a sitemap, whose label is abbreviated (implying either that the label is not shown, because the value is too long, or implying that possibly the value is also abbreviated), the user should see the item’s label and value in their completeness.
• The above does not have to be a click, a tooltip when the mouse is over could also be sufficient.
• When a Selection element is clicked, show in the window, above the set of possible values, also the label of the clicked item.

There should be a way to see the full value and label when not pointing device is utilized and only the tabulator key is used. Currently read-only items have no “tab stop” so they cannot be focused with the keyboard.
