Custom List field (subform) in Custom List field: nested scroll bar reduces usability

[hytsch]

Steps to reproduce the issue

Create a Custom Field X (type: List, Subform Only). Create multiple list entries. Create a Custom Field Y (type: List), and refer to Field X.

Expected result

I expect to be able to see and select the list entries in the admin.

Actual result

Unfortunately Joomla (the default admin template) shows the dropdown too small, it is impossible to see and select entries.

System information (as much as possible)

current Joomla

Could you please add a screenshot? For me everything looks in normal size.

@hytsch Please confirm this is still an issue as I cannot reproduce it. Thanks.

@hytsch Could you check if this is still an issue with the meanwhile latest Joomla version?

I can replicate this issue in my own component. Writing instructions on how to replicate with a core component now

Steps to replicate this

• edit the file administrator\components\com_users\forms\config_domain.xml

• • add this code to create an additional field

    <field
        name="test"
        type="list"
        label="test"
        layout="joomla.form.field.list-fancy-select"
        >
        <option value="1">test1</option>
        <option value="2">test2</option>
        <option value="3">test3</option>
        <option value="4">test4</option>
        <option value="5">test5</option>
        <option value="6">test6</option>
        <option value="7">test7</option>
        <option value="8">test8</option>
        <option value="9">test9</option>
        <option value="10">test10</option>
    </field>

• view the changes by going to the options for the users component and then the second tab called email domain options

• • click on the plus to create a new entry
• • click on the new test field dropdown and you will see the error reported

• edit the file again

• • remove the line layout="joomla.form.field.list-fancy-select"

• view the changes as before

• • there is no scroll issue but of course you have lost the ability to have a searchable list

Conclusion It is possibly something to do with the list-fancy-select layout when used in a subform. Or with the repeatable-table layout as the problem is not present with the repeatable layout
