});
For (var i = 0; i<aData.lenght; i++){
   uiElement.addItem(new sap.ui.core.ListItem({text: aData[i].name}));

If there are any controls, that you are not able to find in SAPUI5, then you can use HTML controls along with them. Also, it is advisable to keep looking for latest version of SAPUI5 as each release have new functions and control which may be useful for you.

SAPUI5 controls are generally developed by wrapping the standard controls.

The wrapper code provides you with more functionality from a business perspective and you can have better control as well. So these definitely have an edge over standard controls in HTML.

Difference between SAPUI5 and HTML5

HTML5 is a markup language and it doesn’t have programming capabilities but SAP UI5 is a framework which is based on MVC approach to build web applications.

HTML5 is mainly for the purpose of creating a simple webpage without formatting and logic but UI5 provides standard style and components to build rich UIs.

You will find render Manager with render method for every control. These controls convert SAPUI5 control to HTML.

Both JQuery and SAPUI5 work on the JavaScript-based framework. SAPUI5 is basically intended to develop applications that are related to other SAP products. These applications can be developed at a very fast pace as compared to JQuery.
