Introduction to Context Filter in Tableau
Filtering is used to access all the data in data source independently. Filtering will help the users to give an insight into the data and provide the search independently. For example – if we want to filter the department according to the employee, at that time we can filter out employees belonging to a different department. This will be helpful for the small database. If we have a data of multinational companies and who has more than 20k employee, then Context Filter in Tableau is the right choice to use in the tableau. We need to add a context filter to the respective dimension. We can create and remove the context filter from the tableau.
How to Create the Context Filter in Tableau?

You can see in the below image, there are more options for the filter. Show filter will display various types of filters available in the tableau such as condition or TOP. If we click on the remove sub-category will be removed from the rows.
When we click on the filter, the filter window will get open. Look at the image below.
We have four options available to the Filter, such as given below with meaning.

- Wildcard – we can match the values from given datasets such as contains, starts with, ends with and exactly. It contains within the dataset. starts with for example – starts with a, b or etc. ends with for example – ends with a, b, etc. exactly for example- exactly as power or any
- Condition – we can define condition means statement with min and max
- Top – Top 10 or 20, etc value and Bottom value 10 or 20, etc. we will have this with Min, Max,

5. Click on the category name and select Add to context.
The category filter name is gets changed to context filter. You can observe now first context filter gets applied then the result is shown y TOP 10 value as per the sub- category.

- Click on remove from
Conclusion
We have learned about filters and context filters. Filters will help users will filter out the dataset as per our choice and when it comes to context filter, it will show us the filtering based on the large database and will provide more accurate result and this will avoid repetitive work. When we apply the context filter, it gets executed in the tableau then the rest of the filters if present in the tableau will get executed. The data source is accessed simultaneously.
