selection of multiple checkboxes with a dropdown

[Muhammad26726881w3ka]

Hello there,

I have stuck in PDF form where i need to select the option-1 from the drop-down menu, the multiple check box (Box1, Box2, Box3) should be auto-populate/auto check.
i have tried it for a single box, and it works for me but I need to select the Multiple boxes with option-1
i have tried this script for a single box, if anyone please help me to amend the script for the selection of multiple boxes
this.getField("B1").checkThisBox(0,event.value == "Choice01" ? true : false);

where B1 is the box1 and the Choice01 is the option-1 in the dropdown menu

Regards

Repeat the script for the other check boxes.
