name |
string |
The name of this VisualElement. Use this property to write USS selectors that target a specific element. The standard practice is to give an element a unique name. |

toolbar |
string |
Text to display inside an information box after the user hovers the element for a small amount of time. |
usage-hints |
string |
A combination of hint values that specify high-level intended usage patterns for the VisualElement.This property can only be set when the VisualElement is not yet part of a Panel. Once part of a Panel, this property becomes effectively read-only, and attempts to change it will throw an exception.The specification of proper UsageHints drives the system to make better decisions on how to process or accelerate certain operations based on the anticipated usage pattern.Note that those hints do not affect behavioral or visual results, but only affect the overall performance of the panel and the elements within. It’s advised to always consider specifying the proper UsageHints, but keep in mind that some UsageHints might be internally ignored under certain conditions (e.g. due to hardware limitations on the target platform). |
view-data-key |
string |
Used for view data persistence (ie. tree expanded states, scroll position, zoom level). This is the key used to save/load the view data from the view data store. Not setting this key will disable persistence for this VisualElement. |
To see which USS selectors affect the components of the DropdownField at every level of its hierarchy, use the UI Toolkit Debugger:
use the Matching Selectors section in the Inspector or the UI Toolkit Debugger.
