TextareaField alternative - GridField / HtmlField?

Silverstripe Version:4.*


Within Admin → Security I added custom fields. And I want to add additional info (List of custom Apps for edited user) that would be represented best with a Html table. The problem with textarea is that it doesn’t support HTML elements (table, new line,…). The solution with TextareaField works but I cannot format it to what I need. I tried with GridField but I don’t know how to prepare the needed Object from the query. Is there an alternative (Something like HtmlField) I could use? Or a simple way to create an array to the object for GridField?

class MyMemberExtension extends DataExtension
private static $belongs_many_many = [
        'LeftMenus' => LeftMenu::class,

public function updateCMSFields(FieldList $fields)
   $fields->push(new TextField('VsMemberID', 'VS member ID'));
   $fields->push(new TextField('NdaSignedDate', 'NDA Signed Date'));
         'VS apps for user',
         // LeftMenu::get()

private function getAllAppsForUser()
   $editedMemberId = $this->owner->ID;
   $query = new SQLSelect();
   $result = $query
      ->selectField('"LeftMenu"."AppName"', 'AppNames')
      ->selectField('"LeftMenu"."AppIND"', 'AppID')
      ->addInnerJoin('leftmenu_members', '"leftmenu_members"."LeftMenuID" = "LeftMenu"."ID"')
      ->addWhere(['leftmenu_members.MemberID' => $editedMemberId])

   $res = array();
   $i = 0;
   foreach ($result as $value) {
      $res[$i] = $value['AppID'] . ' ' . $value['AppNames'];
   return implode('; ',$res);

I ended up using GridField. :slight_smile:

Just for future reference, the LiteralField supports HTML
