Advanced Search filter (Angular 10)

[jefferson simon]

Hey there guys,

I wanted to develop a advanced search filter where we can actually compare two keys

e.g: Category = subcategory, category != Subcategory

Idea is to have all these in single input field as autocomplete drop down one after other selection the selected key will displayed as chips in the input field.

If anyone can help to achieve this in angular 10, please let me know

Concept inspired by : gitLab
