Creating a 'tooltip' for variables in a Choice list - Model Builder/GeoProcessing

[JustinGleeson]

Hi,

I've created a GeoProcessing task that allows users to select a series of variables from a choice list. The results of which are sent into a raster calculation process.

Unfortunately the variable names are very long and I'd like to be able to use an abbreviated version of the variable names and have a tooltip displaying the full name when the user does a mouse over. Another alternative would be to use a Label but for some reason I can't get either of these to work.

For example, National_Inventory_of_ArchHeritage would become 'NIAH' as the variable name with a tool tip displaying ‘National Inventory of Architectural Heritage’.

See image below and a snippet from the widget config containing the variables

<param type="multivalue:string" name="Water" required="true" visible="true"  label="Water">

            <choicelist>

                <choice value="Aquifer_Vulnerability" />

                <choice value="GroundSource_Protection_Areas"/>

                <choice value="RPA_Recreational_WaterAreas"/>

                <choice value="RPA_Recreational_WaterLakes"/>

                <choice value="WFD_GroundwaterStatus"/>

                <choice value="WFD_NutrientSensitive_LakeStatus"/>

                <choice value="WFD_NutrientSensitive_RiverStatus"/>

            </choicelist>

        </param>

Any suggestions or comments welcome

Thanks

Justin
