    How do I use conditional logic to auto select items from a check box list?

    Asked by oztechs on July 06, 2016 at 10:06 PM

    I have a form with 2 checkbox fields.


    Checkbox Field A

      Example 1
      Example 2
      Example 3

    Check box Filed B

    Option 1
    Option 2
    Option 3
    Option 4
    Option 5

    When i select Example 1 I want Option 1 and 2 to be pre selected.

    When I choose Example 2 then I want Options 2 and 4 auto selected.

    So when I use the conditional logic I can only say If Field A is equal to Example 1 then enable ... and that is where my problem I can only enable the entire widget and I can't specify: Field B, Option 1, Option 2.


    Is there away to achieve that?


    Thank you,

    Unfortunately this is not possible, you can only copy the selection from one check box to another one, but fields must have the same options in order to copy the selected option. 

    Here is a sample form that I made to show you how it works: https://form.jotform.com/61878285666979 

    This seems to be the only way to handle two different check boxes, otherwise you will need to get the source code of your form and add your custom script code to achieve it.

    Hi OZ.

    Here's the form I experimented with

    The 1st one on top is based on your specs (no action is given on the 3rd checkbox). 
    If Example 1 & 2 are both selected, pre-selected choices are 1, 2 & 4.

    The 2nd one at the bottom uses a radio button for triggers instead of check boxes. 

    I used the old platform (www.jotform.com//?old) since I'm still not accustomed with the new one.

    Hope this helps.

    Thank you Randy for providing this great workaround. 


    Once you clone the form Randy provided, you can inspect conditions that are set inside of the form. All conditions that were used are Update / Calculate Field. 

    If you have difficulties with applying this to your form, please provide us ID of the form you are working on and tell us which fields you want to pre-select based on another field selection. 

    Let us know if you need further assistance.
