Thanks for the clarification,
So I know have to remove the default editor stylesheet and replace it with a small stylesheet that will have below css
ul {
display: block;
list-style-type: disc;
-webkit-margin-before: 1em;
-webkit-margin-after: 1em;
-webkit-margin-start: 0px;
-webkit-margin-end: 0px;
-webkit-padding-start: 40px;
}
after this i will simply click on bullet list icon in editor to get a bullet style list ?
