Hun har det ikke med at klage, men hun er generøs og hjælpsom, når andre har travlt.

Har det med at is an idiomatic expression meaning to tend to, to be prone to, or to have a habit of doing something.

So:

• Hun har det med at klage = She tends to complain
• Hun har det ikke med at klage = She is not the type to complain / She doesn’t tend to complain

It is more about a person’s general tendency or character than about one specific moment.

In this expression, det does not refer to a specific thing. It is just part of the fixed idiom have det med at.

So you should learn it as a whole chunk:

• have det med at + infinitive

Examples:

• Jeg har det med at glemme navne. = I tend to forget names.
• Han har det med at komme for sent. = He tends to arrive late.

You usually cannot translate the det literally in English.

Because the full pattern is:

• have det med at + infinitive

So the verb that follows comes in the infinitive form with at:

• at klage
• at glemme
• at overdrive

Examples:

• Hun har det med at grine højt.
• De har det med at vente til sidste øjeblik.

Even though med is a preposition, the expression as a whole requires at + infinitive.

There is a nuance difference:

• Hun klager ikke = She doesn’t complain
  
  • This can refer to a fact in general, or to a specific situation.
• Hun har det ikke med at klage = She isn’t the kind of person who complains / She doesn’t have a tendency to complain
  
  • This sounds more like a character trait or habitual behavior.

So the sentence is not just saying that she is silent this one time. It suggests that complaining is generally not her style.

They are predicative adjectives, meaning they come after er and describe the subject.

In Danish, predicative adjectives often agree with gender/number:

• common singular: usually no extra ending
• neuter singular: often -t
• plural: often -e

Here the subject is hun, which is singular and refers to a common-gender person, so the basic forms are used:

• hun er generøs
• hun er hjælpsom

Compare:

• et barn er hjælpsomt
• de er hjælpsomme

Hjælpsom means helpful or willing to help.

It often describes someone’s personality, not just one action.

Examples:

• Hun er meget hjælpsom. = She is very helpful.
• En hjælpsom kollega = a helpful colleague

So in this sentence, generøs og hjælpsom describes her as both generous and ready to help others.

Have travlt is a very common Danish expression meaning to be busy, to be in a hurry, or to have a lot going on.

So:

• andre har travlt = others are busy

Danish usually says have travlt, not være travl, in this everyday sense.

Examples:

• Jeg har travlt i dag. = I’m busy today.
• Vi har meget travlt på arbejdet. = We’re very busy at work.

You may sometimes see travl as an adjective in other structures, but have travlt is the normal phrase learners should remember.

Andre means others in a general sense.

• når andre har travlt = when others are busy

If it said de andre, it would usually mean the others, referring to a more specific known group.

Compare:

• Hun hjælper andre. = She helps others.
• Hun hjælper de andre. = She helps the others.

In your sentence, andre is more general and natural.

Når often means when in the sense of whenever or at times when.

In this sentence:

• når andre har travlt = when/whenever others are busy

It suggests a repeated or typical situation, not one single past event.

Very roughly:

• når = when/whenever, generally or repeatedly
• da = when, for a specific event in the past
• hvis = if

So når fits well because the sentence describes her usual behavior.

This is normal Danish word order in a main clause.

The finite verb is in second position:

• Hun = subject
• har = finite verb
• det = part of the idiom
• ikke = negation

So:

• Hun har det ikke med at klage

This is more natural than trying to put ikke earlier.

Learners often want to compare it with English, but Danish negation placement follows Danish sentence structure, especially the V2 rule in main clauses.

In normal Danish, no. You need the subject again after men:

• Hun har det ikke med at klage, men hun er generøs og hjælpsom ...

Danish usually repeats the subject in the second coordinated clause unless the structure allows omission very naturally. Here, repeating hun is the standard and clearest form.

In Danish, the infinitive of a verb is often shown by at + verb:

• at klage = to complain
• at hjælpe = to help
• at være = to be

In dictionaries, verbs are usually listed in this form. So if you see at klage, you can identify it as the infinitive.

In this sentence, the infinitive is required by the expression have det med at.

It is neutral natural Danish. It sounds like ordinary written or spoken Danish.

A few parts give it a slightly thoughtful or descriptive tone:

• har det ikke med at is a natural idiomatic expression
• generøs og hjælpsom sounds like a character description

So it would fit well in everyday conversation, a description of a colleague or friend, or normal written prose.
