Hi Manmath
It really depends where you are using this, so if you are using the Editable Text web part, then you can amend the settings to use instead of Inline Toolbar, you can change it to use a Shared Toolbar. This is a setting in that web part.
If it is a Page Type field, then you can also change the Toolbar location between the values Out, None or Default.
Another issue could be from your CSS potentially conflicting the toolbar placement and finding the appropriate styles to not conflict them when in EditMode. If this is the case, if you can provide more information and I can help further.
I hope this helps.
Thanks
Ilesh
