I have a drop down list and want to filter options when entering a specific value in the Text box.
Hi @Anonymous ,
Do you want to filter the drop down's Items based on the textinput?
Could you tell me:
1)the drop down's Items?
2)the field data type that you want to filter based on?
I assume that you set the drop down Items to a table name and the field is text type.
If so, I've made a similar test for your reference:
set the drop down's Items:
If(IsBlank(TextInput1.Text),list1,Filter(list1,TextInput1.Text in Title))
//filter Title field based on the data in textinput1
Best regards,
