    It’s nothing specific to CMB2, but you could pass in the a maxlength attribute to be appended to the field input. https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes

    Hey Michael,

    Just wondering – how would I go about passing the maxlength attribute to be appended to the field input? Not sure where to start.

    Thanks!

    ogdsgn, this will work on text inputs, despite the example being a textarea.

    $cmb->add_field( array(
    'name'        => 'Extra Small Textarea',
    'id'          => 'wiki_test_xtra_small_textarea',
    'type'        => 'textarea_small',
    'attributes'  => array(
        'placeholder' => 'A small amount of text',
        'rows'        => 3,
        'required'    => 'required',
    ),
) );

    Note the “attributes” portion. You can add extra html attributes to ANY of the field types like this, including maxlengh.
