How to enlarge database name area in odoo? | OpenERP

You can enlarge the area by changing max-width value of .openerp .oe_topbar .oe_topbar_name class which is inside base.css file. For that you have to overwrite that class.

So create one css file inside your_module/static/src/css folder and add following code:

@charset "utf-8";
.openerp .oe_topbar .oe_topbar_name {
 max-width: 190px;
 overflow: hidden;
 display: inline-block;
 max-height: 100%;
 text-overflow: ellipsis;
 white-space: nowrap;
}

Go to __openerp__.py and add your css file under css like this:

'css': [
    'static/src/css/my.css',
],

Now, restart your server and refresh the page.

Here, max-width: 150px; was given in base.css and now we are changing it's value as per our need. I changed it by190px. You can change it to any value which is suitable to you.
