Add default blank value for select option in contact form 7 wordpress

Normally when you use contact form 7 plugin , for dropdown select option, there is no option to set blank value for the first option to validate the select field.

For example, what we have in wordpress contact form 7

<select name=”your_field_name”>
<option value=””>—</option>
<option value=”yes”>Yes</option>
<option value=”no”>No</option>
</select>

But in actual scenario, i want to display the label for the first option as “–Select Value–” with empty value.
To make the same change, you can use the dropdown code as below
[select* your_field_name_ class:form-select class:required first_as_label “–Select Value–” “Yes” “No”]

In the above code “first_as_label” is important parameter. It instruct the plugin to use the first option as label with default empty value. So the generated output look as below

<select name=”your_field_name”>
<option value=””>–Select Value–</option>
<option value=”yes”>Yes</option>
<option value=”no”>No</option>
</select>
