How to Select multiple related columns in add calculated fields in Quicksight parameter using ifelse ?

Question

Hello everyone,

I have a parameter **'type'** in a table and it can have multiple values as follows - 
1. human
2. chimpanzee
3. orangutan

I have 3 columns related to each type in the table - 
1. human_avg_height, human_avg_weight, human_avg_lifespan
2. chimpanzee_avg_height, chimpanzee_avg_weight, chimpanzee_avg_lifespan
3. orangutan_avg_height, orangutan_avg_weight, orangutan_avg_lifespan

So if i select the **type** as **human**, the quicksight dashboard should only display the three columns - 
1. human_avg_height, human_avg_weight, human_avg_lifespan

and should not display the following columns - 
1. chimpanzee_avg_height, chimpanzee_avg_weight, chimpanzee_avg_lifespan
2. orangutan_avg_height, orangutan_avg_weight, orangutan_avg_lifespan

I created the parameter **type** and in the add calculated fields I am trying to use `ifelse` to select the columns based on the parameter selected as follows -

`ifelse(${type}='human',{human_avg_height}, {human_avg_weight}, {human_avg_lifespan},{function})`

I also tried -

`ifelse(${type}='human',{{human_avg_height}, {human_avg_weight}, {human_avg_lifespan},{function}})`

And -

`ifelse(${type}='human',{human_avg_height, human_avg_weight, human_avg_lifespan},{function}})`

But none of it is working. What am i doing wrong ?

Answer

To achieve this usecase, you can use 3 calculated fields in your visual:

**height**
```
ifelse(${type}='human',{human_avg_height},
${type}='chimpanzee',{chimpanzee_avg_height},
${type}='orangutan',{orangutan_avg_height},
NULL)
```

**weight**
```
ifelse(${type}='human',{human_avg_weight},
${type}='chimpanzee',{chimpanzee_avg_weight},
${type}='orangutan',{orangutan_avg_weight},
NULL)
```

**lifespan**
```
ifelse(${type}='human',{human_avg_lifespan},
${type}='chimpanzee',{chimpanzee_avg_lifespan},
${type}='orangutan',{orangutan_avg_lifespan},
NULL)
```

In the visual, you can use these fields - **height, weight, lifespan** that would change depending on the **type** parameter.

Please try the above and let me know if it helps. Thank you!
