Read MoreStatic HTML elements are written directly in SAPUI5
SAPUI5 allows developers to use their own static HTML elements alongside UI5 controls. It is not a closed framework − you can use the sap.ui.core.HTML control to write plain HTML within any area rendered by UI5, making it easy to mix static HTML and UI5 controls in the same view. HTML created by UI5 controls is generated dynamically at runtime. This is how most JavaScript UI libraries work when providing higher-level UI elements that would be complex to write in static HTML alone. However, SAPUI5 gives you the flexibility to embed your own static HTML whenever needed. ...

To handle multiple submit buttons, we can use the formaction attribute, assign the same name with different value attributes, or give each button a different name. The server-side code then determines which button was clicked and processes accordingly. Syntax Using formaction Attribute Default Action ...
