Bootstrap in TB Mega Menu
TB Mega Menu is developed with a customized version of Bootstrap (built-in). The reason behind having a customized Bootstrap is to prevent any conflicts between TB Mega Menu's and currently used theme's css style that could ruin partially/totally the whole design of either/both component(s).
