To mark a field is required with red *

[mch8418]

Hi, how can I mark a field that is mandatory with a red *?

Hi there,

You may check out:

Form Validation

Or simply add the asterix (or red border) by testing for valid input in code with IF statements.

Can you share what you have tried?

One way is, if you have a label and a text box together, to add an icon to the label (eg fa:star) and set icon_align to right (either in code or in the properties in the IDE).

If you could kindly show an example of what you have attempted so far we would be happy to provide assistance. Perhaps you could share a clone link or a somewhat complete block of code (this is good practice on the forum).

This was something I did a little while back:

Making mandatory text boxes obvious

Here’s a quick and simple way to put a red border on a text box that’s mandatory but hasn’t been completed: In Theme, Assets, go to ‘Configure roles…’, add a new role and add ‘TextBox’ to its component types. I called mine ‘mandatory-textbox’ Add two entries to ‘theme.css’: .anvil-role-mandatory-textbox:placeholder-shown { border: 1px solid red; } .anvil-role-mandatory-textbox:-ms-input-placeholder { border: 1px solid red; } The second entry is to make this work on Internet Explorer and…

@owen.campbell I don’t see ‘Configure roles’ when I go to ‘Theme’ --> ‘Assets’. Was that removed?

[david.wylie]

You configure roles in Theme -> Roles

I don’t recall it even being under assets (though I am old and peculiar).

I am old enough to be bordering on senile. That may have been correct at time of press or might simply be the onset of variant CJD.

Was this question answered? Can radio buttons be required?

In the general case, I typically add a Label, color it “red”, and set its text to “*”, then place the label where it belongs.
