Magento 2 Add Category Tree Renderer Input With Modal Button

Question

I am trying to place the category input for my custom form using uicomponent form.

I am able to create dropdown but how I can create the button and open a new modal from it?

Can I create a button using uicomponent and open a modal from it. I want a button instead of new category I want to add select products button and want to add show list of products from selected categories in grid.

Here is the xml for creating the category input

<field name="parent">
    <argument name="data" xsi:type="array">
    <item name="options" xsi:type="object">Magento\Catalog\Ui\Component\Product\Form\Categories\Options</item>
     <item name="config" xsi:type="array">
          <item name="label" xsi:type="string" translate="true">Parent Category</item>
          <item name="componentType" xsi:type="string">field</item>
          <item name="formElement" xsi:type="string">select</item>
          <item name="component" xsi:type="string">Magento_Catalog/js/components/new-category</item>
           <item name="elementTmpl" xsi:type="string">ui/grid/filters/elements/ui-select</item>
           <item name="dataScope" xsi:type="string">data.parent</item>

This code below working with me:

     <container>
        <argument name="data" xsi:type="array">
            <item name="config" xsi:type="array">
            <item name="formElement" xsi:type="string">container</item>
            <item name="component" xsi:type="string">Magento_Ui/js/form/components/group</item>
        </item>
        </argument>
        <field name="category_ids">
            <argument name="data" xsi:type="array">
                <item name="config" xsi:type="array">
                    <item name="dataType" xsi:type="string">text</item>
                    <item name="filterOptions" xsi:type="boolean">true</item>
                    <item name="chipsEnabled" xsi:type="boolean">true</item>
                    <item name="label" xsi:type="string">Categories</item>
                    <item name="disableLabel" xsi:type="boolean">true</item>
                    <item name="component" xsi:type="string">Magento_Catalog/js/components/new-category</item>
                    <item name="formElement" xsi:type="string">select</item>
                    <item name="levelsVisibility" xsi:type="number">1</item>
                    <item name="elementTmpl" xsi:type="string">ui/grid/filters/elements/ui-select</item>
                    <item name="options" xsi:type="array">
                            <item name="0" xsi:type="array">
                                <item name="value" xsi:type="number">1</item>
                                <item name="label" xsi:type="string" translate="true">Category 1</item>
                                <item name="optgroup" xsi:type="array">
                                    <item name="0" xsi:type="array">
                                        <item name="value" xsi:type="number">2</item>
                                        <item name="is_active" xsi:type="boolean">true</item>
                                        <item name="label" xsi:type="string" translate="true">Category 1.1</item>
                                    </item>
                                </item>
                            </item>
                            <item name="1" xsi:type="array">
                                <item name="value" xsi:type="number">2</item>
                                <item name="is_active" xsi:type="boolean">true</item>
                                <item name="label" xsi:type="string" translate="true">Category 2</item>
                            </item>
                    </item>
                   <item name="config" xsi:type="array">
                       <item name="dataScope" xsi:type="string">category_ids</item>
                   </item>
                </item>
            </argument>
        </field>
    </container>

This is result:

Note: With item options you should change xsi:type="object" and declare a Class for it.

I hope it was helpful !
