# Option: auto_reset_designmode

This option is very useful if TinyMCE is used in a DHTML tab system or other divs that are hidden and displayed by some JavaScript. Since Mozilla has a bug when using display:none, the designMode state gets lost. To prevent this from happening you should enable this option. The default value of this option is "true".

### Example of usage of the auto_reset_designmode option:

    tinyMCE.init({
        ...
        auto_reset_designmode : true
    });
