Made it working. Thanks for the tip.
Using firebug, i got the div name of the button panel, then used the jquery to set the button panel dragable.
i replaced the jquery-ui found in your folder, with the full jquery-ui package from official site(just in case). and changed the background color and area of the div to make its area recognizable.
Now here is the catch, The deviation added in the textarea after initilization(around 20px) remains there . Where in the plugin, i have to make the changes for position to absolute so that my layout is not disturbed in the webpage.
If i am allowed, I want to write these changes in the core so that i can use it in future. also i where in the core can i write the draggable property so that it become part of the plugin for future.
I highly suggest that draggable property should made as part of this plugin in the future. I tried around 30 plugin for college project before i finally came across this one. I am quite sure that
draggable button-panel is not a common feature in editors, i came across only 2 editors but they weren't for markdown.
Anyways. This is a great, powerful and very simple plugin for non-expert. Thanks.
This is the link of what i was trying for college project.
