Hello,

I need to change values of field 2 depending on the selection of field 1.

Field 1: type

Field 2: category

<xpath expr="//div[2]" position="after">
    <div class="form-group">
        <label class="col-md-3 col-sm-4 control-label" for="type">Type</label>
        <div class="col-md-7 col-sm-8">
            <select class="form-control" id="type" name="type">
                <t t-foreach="types" t-as="cate">
                    <option t-attf-value="#{cate.id}">
                        <t t-esc="cate.name"/>
                    </option>
                </t>
            </select>
        </div>
    </div>
</xpath>
<xpath expr="//div[4]" position="replace">
    <div class="form-group">
        <label class="col-md-3 col-sm-4 control-label" for="category">Category</label>
        <div class="col-md-7 col-sm-8">
            <select class="form-control" id="category" name="category" required="True">
                <t t-foreach="category" t-as="cat">
                    <option>
                        <t t-esc="cat.name"/>
                    </option>
                </t>
            </select>
        </div>
    </div>
</xpath>


I would appreciate any explanation or example of how this type of action should be developed.

Thank you
