If you want to hide the Clear and/or Reset buttons that are automatically attached to popup configurators, you can do so by creating a new element in the configurator logic and then setting that action to be hidden.
Clear Button
Groovy
import net.pricefx.common.api.InputButtonAction
def ce = api.createConfiguratorEntry()
ce.setHiddenActions(InputButtonAction.CLEAR)
return ce
Reset Button
Groovy
import net.pricefx.common.api.InputButtonAction
def ce = api.createConfiguratorEntry()
ce.setHiddenActions(InputButtonAction.RESET)
return ce
If you are removing both, put these in two different elements. Also, you can leave the visibility of the elements as visible Everywhere.
