How to Foce Selection of Characteristics

Hi,
Can someone please tell me how to force characteristics within a product, for example wthin the drop down menu to display:

Please select
option 1
option 2
option 3

I have looked everywhere and can not find out how to enable this.

Any help would be greatly received.
Thank
Phil

Hi,

You can create a characteristic with 4 values, the first one being the "please select".
Then, after you add the characteristic to the product, select the "please select" value as the default value of the characteristic and then, click on the "manage variants" button and edit the variant for the "please select" value and set a quantity of 0.
That way the default one will be "please select" and it won't display the add to cart button until the user select something else in the characteristic dropdown.

Works Perfectly, Thank you
