Sublime Text built intellisense for html, even when editing .erb files. This is even a fuzzy match instead of exact substring matching, like most intellisense tools.
- Make sure your syntax is html (rails). Press
ctrl+shift+p and type Set Syntax: HTML (Rails) - Press
ctrl+space when you want intellisense popup menu
If you want intellisense to pop up automatically, rather than pressing ctrl+space , you can change the "auto_complete_triggers" parameter in the .sublime_settings settings. For example, if you want the intellisense popup to appear after entering < or = , you must add it to your user settings file:
"auto_complete_triggers": [ {"selector": "text.html", "characters": "<="} ]
