shapefile - Merging attribute and geometric features in QGIS?

I have polygons shapefile in which some of the polygons have same attributes as seen below:-

In QGIS, how do I merge the polygons having the same attributes into one polygon?

In other words, am looking for a way to merger polygons/attribute of the same layer, that is similar way of merging vector layers found at: Vector >> Data Management Tools >> Merge Vector Layers

Answer

You can use the Singleparts to Multiparts in the Vector Geometry tools section of the processing toolbox to do this. It will prompt you for the input layer (from a dropdown list) and the Unique ID field (Ward Code) and you can specify an output file name.
