text field remove default when user inputs data

[thodoris]

Hello,

I have a text field in my db with a default instructive text like
"Enter your comment here", but i would like when the user tries to
input text, the default text to disappear without having to delete it
manually

You can use a comment instead of a default:

    Fields(..., comment='Enter your comment here')

though that will display next to or below the input field (depending on your formstyle) rather than in the text box itself.

As an alternative, you can set the HTML5 'placeholder' attribute for the input field by customizing the field's widget:

    Field(...,

        widget=lambda f,v: SQLFORM.widgets.text.widget(f, v, _placeholder='Enter your comment here'))

Thnx a lot!

Is there a similar widget that works for the string?

Because when I do the following, it doesn't work

Field(...,

        widget=lambda f,v: SQLFORM.widgets.string.widget(f, v, _placeholder='Enter your comment here'))

Works for me. Must be a problem somewhere else in your code.

You are right. I forgot to mention, I was trying to work it with 'list:string'

And it breaks the list.
