+The user can control and specify the links allowed for creation in each link field. The `setAllowedTypes` method only includes link types that have been provided as parameters.
+
+```php
+<?php
+use SilverStripe\CMS\Model\SiteTree;
+use SilverStripe\LinkField\ORM\DBLink;
+use SilverStripe\LinkField\Models\Link;
+use SilverStripe\LinkField\Form\LinkField;
+use SilverStripe\LinkField\Form\MultiLinkField;
+use SilverStripe\LinkField\Models\FileLink;
+use SilverStripe\LinkField\Models\SiteTreeLink;

+{
+    ...
+
+    public function getCMSFields()
+    {
+        $fields = parent::getCMSFields();
+
+        ...
+
+        $fields->addFieldsToTab(
+            'Root.Main',
+            [
+                MultiLinkField::create('HasManyLinks')
+                ->setAllowedTypes([ SiteTreeLink::class ]),
+            ],
+        );
+
+        return $fields;
+    }
+}
+```
+
+
+Additionally, users have the option to designate links for exclusion from the available choices in the specific field. The setDisabledTypes method omits link types provided as parameters from the complete list of link types.
+By default, all types of links are available.
