A simple list group consists of an unordered list with individual list items.
Apply the .active class to indicate the currently selected item.
For a list group with links, use <div> in place of <ul> and <a> instead of <li> You can also add the .list-group-item-action class to enable a grey hover effect.
The .disabled class gives disabled items a lighter text color and removes the hover effect on links.
Apply the .list-group-flush class to eliminate certain borders and corner rounding from the list group.
Use the .list-group-numbered class to create list items with numbers in front of them:
To display list items side by side instead of stacked, add the .list-group-horizontal class to the .list-group element
Use .badge along with utility classes to place badges within list group items.
