I am trying to create a datetime picker in a form using o_website_form_datetime, but the problem is that, the input field doesn't show the popup to enter the date and time.
This is the code for my input:
<input id="date_time_funeral" type="text" name="date_time_funeral" class="form-control o_website_form_datetime" t-att-value="date_time_funeral" data-date-format="DD.MM.YYYY HH:MM" style="text-align: center;" autocomplete="off" required="true"/>
I took the code from an odoo 10 project, and there it works with no problem.
I am avoiding to use type="datetime-local", since it is not supported by all browsers.
