[Vuejs]-Filter data from nested array in vue.js

Currently you are filtering faq so for each item you are going to take either all its content or none.

You could do something like this:

function filterfaq () {
  const search = this.searchValue.toLowerCase().trim();
  if (!search) return this.faq;
  return this.faq.map(item => {
    return {
      ...item,
      content: item.content.filter(question => {
        return question.qus.toLowerCase().includes(search);
      }),
    }
  });
}
