How to Hide button in the opportunity module menu with specific criteria (Sugar 7)?

Try this:

({
    extendsFrom: 'RecordView',
    render: function (options) {
        app.view.invokeParent(this, {type: 'view', name: 'record', method: 'render', args: [options]});

        var salesStage = this.model.get('sales_stage');

        if (salesStage != 'Verbal Conf') {
            $('a[name=test_form]').hide();
        }
    },
})

This way your code will execute after render instead of after initialization.

BTW, when you said it didn't work, what did work? Try putting a 'debugger;' comment before if (salesStage != 'Verbal Conf'){     - that way you can check whether salesStage is populated. If it is populated, then the problem is with your javascript, else your problem is with populating salesStage. Which is it?
