[SOLVED] dropdown empty value

Hello,

I'm searching a way (I didn't find in the doc or here) to display a string on a dropdown value as this :

Displayed value "Please select a value" (equal no choice)
choice one : A
Choice two : B
Etc...

Do you have any idea to make this ?
Thx for answers

A blank value? No, that's not possible. The blank value is automatically added internally and it has no label. It's based off the field being required or not. Allowing a custom blank value would break the validation. You could do something like the below by using a language string.

Value: UE_PLEASE_SELECT_VALUE

'UE_PLEASE_SELECT_VALUE' => 'Please select a value'

Next you'd use CB Conditional and condition the fields profile display and if its value is equal to UE_PLEASE_SELECT_VALUE then hide it.

Well as I answer in the french forum I use a similar way but with delimiter field Meybe it could be a good idea to add a option in this kind of field in CB 2.0.
As we have a Pre-filled default value at registration in the list of settings, may be we could also have a blank value ?

With CB 2.0 the value and label can be separate so you'd do the below.

Value: 0
Label: Please select a value

Then in your layout you can have an if check for it like the below.

[cb:if cb_select!="0"][value][/cb:if]

There's a lot more options available for CB 2.0 to accomplish this. For CB 1.x you can use CB Conditional or a delimiter field.

As we have a Pre-filled default value at registration in the list of settings, may be we could also have a blank value ?

That parameter is to set the default selected value at time of registration. It only works if the field is displayed on registration. It doesn't add a new option or anything of the sort.

Excellent , exactly what I want !

I know that, it was a suggest for CB2 but you have answered for that. I must find a moment to install CB2 and test it. I said it to Beat during the JoomlaDay in Paris but I was in hurry last two months. It will be easier in two weeks
