Intellij - Maven's pom.xml doesn't suggest(autocomplete) when injecting dependency

I'm new to Intellij IDEA. I have a small error when dealing with pom.xml file. It seems that Intellij only find and suggest(autocomplete) when i inject a dependency comes from local repository. If I inject any other dependencies that not is not provided in the local repo but from remote repo ( for example in my spring boot web project, apart from dependencies like JPA, Spring Web, Thymeleaf, I want to inject org.webjars:bootstrap:4.1.3 for bootstrap), pom.xml does't suggest the dependency for me. If I force to type the dependency, it raise the compile error: Dependency 'org.webjars:bootstrap:4.1.3 for bootstrap' not found. There won't be any problem if i rebuild the maven( mvn clean install ), but it takes effects only with downloaded jars. I wonder if there are any ways intellij pom.xml can suggest for me and not raise any compile error. Thanks, everybody and wish all of you a nice day
