Development Points
Since AMegMen supports 3 levels, following points are considered during the development:
- Levels start from 0, just like an array.
Root->Level 0 UL/LI->Level 0 Anchor and Level 0 Subnav PanelLevel 0 Subnav Panel->Level 0 Landing link and Level 1 Panel ColumnsLevel 1 Panel Columns->Level 1 UL/LI -> Level 1 Anchor and Level 2 Subnav PanelLevel 2 Subnav Panel->Level 1 Landing link and Level 2 a Single Panel ColumnLevel 2 Panel Column->Level 2 UL/LI->Level 2 Anchor- All Subnav panels must have columns in them, to position the 3rd level accurately.
- Mobile devices don't support hover, so the hover behavior is implemented as an option, which if required, can be enabled by passing
actOnHoverastrue. - Right to Left is based on just a CSS property
direction: rtl, and it may not be supported on old browsers. - Actual code resides in Typescript, which is compiled to Javascript (ES3 and NO Module code generation) and is compressed through Uglify-JS.
- Styles reside in SASS files with minimum configurations and changes mobile to desktop view at 768px. The styles are compressed through UglifyCSS.
