I want to show two text boxes based on selection of a radio button using SWT Widget. However, when I will select another radio button, the previous textboxes should be hidden and a dropdown should be displayed. I am able to achieve the functionality using setVisibility(true) and false. The main problem here is that when the textboxes are not displayed, the space for them is getting consumed and the dropdown is coming below that based on selection of 2nd radio button . I don't want to waste that much space and want the layouts to overlap and consume a common space allotted to them since both can't be used at the same time.

Place the text-input and the combobox on parent Composite using FillLayout.
