    The phone number field will not size properly if I use the (###)###-#### mask on my email sign-up form

    I've tried to edit your form and its seems its working. :)


    Please find this to your CSS in the Form Styles.

    [data-type='control_phone'] :first-child.form-sub-label-container {
    width: 32.5%; margin-right: 2.5%;

    and change that to this new one

    [data-type='control_phone'] :first-child.form-sub-label-container {
    width: 70%; margin-right: 2.5%;

    Note: There are two(2) the same codes in your CSS, please change that also.

    Hope this helps.

    I'm not sure if I understood you correctly, are you referring to the input mask format or is it the width size of the Phone number field? Please do check if the changes I made applies to what you are looking for.

    I've cloned your form for testing purposes.

    1. I enabled the Input Mask and add the Mas Value format that I want.

    2. You can also click the gear icon of the Phone field and you will see additional options in the Properties.

    3. If you are referring to the width size of the Phone number field, I noticed that it is 'shrink', you will need to click the 'Expand' option so that the field may be wider.


    You can check the sample cloned form here: http://form.jotformpro.com/form/43227698548974

    If that is the expected action you are looking for you can clone my form using this guide: http://support.jotform.com/help/42-How-to-Clone-an-Existing-Form-from-a-URL 


    I hope this helps. Let us know if you need further assistance on this.

    Thank you.
