tinyMCE 4.7 Plugin - like .NET IntelliSense

Hello, i'm searching for a developer who can creates an tinyMCE Plugin - it must work with the current tinyMCE version. The workflow must be like .NET IntelliSense Please place a real bid - it can be also higher as 250USD - but please calculate carefull the time you need for this plugin, it should be realistic. If you have some bettzer ideas for the workflow described belowe - inform me, if it make sense, we can change it Workflow description: 1. right click in tinymce open an custom menu - add in the menu as first item "Custom var" 2. on click on this item open a dropdown on the cursor position (below the cursor) - like IntelliSense makes it [login to view URL](v=vs.140).jpeg?f=255&MSPPError=-2147217396 3. on typing an char in tinymce show only the items in the dropdown which starts which this char - or chars. backspace - if no chars typed in - or all chars in the word are deleted close the dropdown on click to another place in text - close the dropdown (see right click menu - it close too if you click on an another place in text) if the cursor prepends with a whitespace - only open the dropdown if there are some chars before the cursor - show only the matched items in the dropdown 4. on enter - if there is an matching word in the dropdown - auto insert this word - appended with a "." point - and open the next dropdown - if avaiable in the json object 5. if no matching word - close the dropdown 6. if the selection of the variable is completed (the json object has a value assigned for this selection) - so replace the variable (for example [login to view URL]) to the value assigned in the json object and mark it with a color. So [login to view URL] will be for example then a "240" with a blue background color 7. if somebody clicks on this marked "240" - and clicks in the right klick menu on "custom var" the original variable "[login to view URL]" should be showed. Technical: 1. use an js object in an extra file for the dropdown list 2. the object can have some sub and sub objects to show the dropdown for example for [login to view URL] 3. each subitem can - but must not have a description with for example a value (like in the image) Thank you BR Denis
