Hi Iqbal Kaur,
first you can add html snippet to that particular page and here is the piece of code
Please see the below screen shot, I want to get rid from the first progress bar which is by default and page doesn't look good with two progress bars:
Let me explain it little more: I have a button click to open the page e.g: Location details page, that page has Dataview Loader to load the object which is taking much time.
so when I click on the button to open that page, the page is getting loaded on the screen with two progress bars one is dataview loader bar which is fine. the other one is on the top of the page which is mendix's default progress bar (transparent black bar with dots). I don't want to see that on the page because there is already dataview loader bar on the page.. I guess I am bad in explaining, don't know if you understood what I am trying to say or I confused you more.
