Logic Dynamism
If you want to set a components property dynamically, you will need to use 'logic dynamism'. This is done by selecting the lighting bolt on a components property and setting the control as dynamic control.

When you select the Dynamism
icon a menu will appear with 3 values to choose from (Static
, Variable
, or Code
)

Setting a components property to anything other than a Static
one will result in the dynamism icon being on and green. This gives better clarity and a glance that the properties value is set dynamically.

menu will appear with options of either choosing from props
(properties) or vars
(variables).
