Increase size of 'form_field'-input field in HTML page

#1 by Janina (edited )


do you know whether there exists any possibility to increase the size of the input field in the HTML-page, if it is defined in 'form-fields'?

Or does any workaround exist?

Hi Janina,

What type of input are you referring to?

I imagine that your use case is an open-ended question for which a <textarea> field would be appropriate. If this is so, you can do the following:

Say, your formfield is defined as

    comment = models.LongStringField(

See https://otree.readthedocs.io/en/latest/models.html#field-types: A LongStringField is “for long text strings; its form widget is a multi-line textarea.”

Then, instead of

{% formfield player.comment %}

you can include, say,

<textarea class="form-control" rows="7" id="id_comment" name="comment"></textarea>
{% formfield_errors 'comment' %}

in your HTML template. The “rows” attribute determines the vertical extent of the input field. There is also a “cols” attribute for the field’s width: https://www.w3schools.com/tags/tag_textarea.asp. Importantly, the “name” attribute has to be equal to the formfield’s name (which is “comment” in this example).

See https://otree.readthedocs.io/en/latest/forms.html#raw-html-widgets and https://otree.readthedocs.io/en/latest/forms.html#customizing-a-field-s-appearance.
