it does the following:
– If the page loads, this settings doesn’t do anything;
– If you click on the field, the placeholder goes away;
– If the user leaves the field blank, the placeholder returns. It also binds the specified class name to the input field. I.e., if you fill in as class “placeholder”, and in your CSS is like the following example, the text appears gray.
.placeholder { color: gray; }
To make the placeholder work you need to do the following:
– Enable “Default value” and type in a default value.
– Fill in and enable the field “default value CSS class”. Even if you don’t want to use it, fill it it – even a dummy.
– Enable “validate”. If you don’t want that the specific field gets validated, enter in “min length: 0”.
It looks like this functionality is quite a bit bugged – but it works if you follow the steps above.
