        editor.RichTextEditor.add('conditionIf', {
            icon: '<b>Condition IF</b>',
            attributes: {title: 'Condition IF'},

                const btnClass = pfx + 'btn-prim ' + pfx + 'btn-import'
                const conditionInputHtml = `<div><label for="placeholders">Placeholder:</label><select id="placeholderId" class="block-input">${options()}</select>
