+#### Description
+

+
+```js
+<ComboButton
+  noBorder={false}
+  isDisabled={false}
+  selectedOption={
+    {
+      key: 0,
+      label: 'Select'
+    }
+  }
+  withOptions={false}
+  optionsLength={0}
+  withAdvancedOptions={true}
+  innerContainer={
+    <>Demo container</>
+  }
+  innerContainerClassName='optionalBlock'
+  isOpen={false}
