Change text format without showing tag

[tuankm123]

Hi all,
I would like to change text format without showing tag, for example, when I select "example" and click B button to make it bold, this text will be bold, not show

[B]example[/B]

. How can I do it?

Thanks

I did enable WYSIWYG to do like that. Everything is working, but only <strike> BBCode is not working. When I select a text and click on <strike> button, it show

<strike>text</strike>

, not showing [S]text[/S]

Can you tell me how can I should do?

BBCODES are like this [strike] and not <strike>
