Here we learn how to add or create a UI-Select field using the block method on the Admin form.
Let’s start step by step.
You must have installed Magento 2 custom Module on which you are going to implement this.
Step 1: We need to create the layout file to define the admin form in view/adminhtml/layout/webkulblog_account_edit.xml :
<?xml version="1.0"?>
<!--

<referenceBlock name="page.title">
<action method="setTitleClass">
<argument name="class" xsi:type="string">
complex
</argument>
</action>
</referenceBlock>
</body>
</page>
Step 2: Create the block file, Webkul\Custom\Block\Adminhtml\Account\Edit.php
<?php
/**

* @package Webkul_Custom
* @author Webkul

parent::_construct();
if ($this->_isAllowedAction('Webkul_Custom::accountedit')) {
$this->buttonList->update('save', 'label', __('Save Account'));
} else {
$this->buttonList->remove('save');
}
$this->buttonList->remove('delete');
$this->buttonList->remove('reset');
}
/**
* Retrieve text for header element depending on loaded Group
*

* Check permission for passed action
*
* @param string $resourceId
* @return bool
*/

{
return $this->_authorization->isAllowed($resourceId);
}
}
Step 3: Create the block file, Webkul\Custom\Block\Adminhtml\Account\Edit\Tabs.php
<?php

/**

protected function _construct()
{
parent::_construct();
$this->setId('blog_account_tab');
$this->setDestElementId('edit_form');
$this->setTitle(__('Blog Account Information'));
}
/**
* Prepare Layout
*
* @return $this
*/
protected function _prepareLayout()
{
$block = \Webkul\Custom\Block\Adminhtml\Account\Edit\Tab\BlogAccount::class;
$this->addTab(
'blog_account_info',
[
'label' => __('Blog Account'),
'content' => $this->getLayout()->createBlock($block, 'blog_account_info')->toHtml()
]
);
return parent::_prepareLayout();
}
}
Step 4: Create the block file, Webkul\Custom\Block\Adminhtml\Account\Edit\Tab\BlogAccount.php
<?php
/**

$form = $this->_formFactory->create();
$fieldset = $form->addFieldset(

['legend' => __('Blog Account'), 'class' => 'fieldset-wide']
);
$fieldset->addType('filterselect', FilterSelect::class);
if ($model->getId()) {

$form->setValues($data);
}
$this->setForm($form);
return parent::_prepareForm();
}
/**

public function getOptions()
{
return [
["value" => "1", "label" => "Customer"],
["value" => "2", "label" => "Admin"],

/**

}
Step-5: Add the custom type in block form using $fieldset->addType(‘filterselect’, FilterSelect::class);, This custom type’s “filterselect” field data handling and rendering by block file : Webkul\Custom\Block\Adminhtml\Widget\Form\Element\FilterSelect.php
<?php

Step 7: Create a custom template file which is mentioned in getDefaultConfiguration() method of Step 5, view/adminhtml/web/template/filterselect.html

Step 10: Create a controller file for the save selected option, Webkul\Custom\Controller\Adminhtml\Account\Save.php
<?php

$this->messageManager->addSuccess("User data has been saved.");

} else {
$this->messageManager->addError(
__('Something went wrong while saving the user data.')
);
return $resultRedirect->setPath('*/*/edit');
}
}
}
After this, a ui-select with a search filter using the block method will be displayed on your form.
Change custom type UI select element configuration in Step 4:
Note: Custom field element configuration changed according to the mentioned configuration in getDefaultConfiguration() method of Step 5 file.
$fieldset->addField(
'access_data', //Element Id
'filterselect', //custom type
[
'name' => 'access_data',
'label' => __('Access data'),
'options' => $this->getOptions(),
'multiple' => true,
'required' => true,
] // In array mentioned configuration of element
);
