On the Create Topic screen, you are asked to provide all the necessary information to create a topic.
The default choices made by Console are generally safe for most typical Kafka Production deployments.
If you want to understand more deeply what those parameters are about, here's some recommended reads:

Kafka Cleanup Policies Explained
As per Kafka specification, topic name must only contain the following characters
[a-zA-Z0-9._-] and not exceed 249 characters.
This lets you define how scalable your topic will be for your consumers. In general you want a multiple of your number of brokers.
This configuration helps prevent data loss by writing the same data to more than one broker.
min(3, number of brokers)
The Cleanup policy (along with its associated advanced configurations) controls how the retention of your messages is done.
Use tags to organize your topics and facilitate searching them in Console
Upon toggling the Advanced configuration, you will be shown all the available topic configurations.

Increase the number of partitions for your topic. Number of partitions cannot be decreased.
Adding partitions reshuffles the target partition of messages with a given key. Existing data will stay on the previous partition. Consumers that rely on partition ordering could be impacted.
This lets you delete all records from a topic. This operation is permanent and irreversible.
If you want to only delete all records from given partition, there's a dedicated operation on the Partitions tab of the topic detail.
This lets you delete the topic from Kafka. This operation is permanent and irreversible.
You can help categorize your Topics further using tags.
To tag a topic, click the "Add tags" button from the topic details view and start typing to find available tags.
If the tag you need doesn't exist, a button will appear to create a new tag.
Then, check the tag(s) you want to associate to the topic and click "Apply".
To remove tags, simply click the "X" icon on the tag name. No confirmation.
Resource tagging is a power filtering feature that helps your organization & projects structure their resources.
